A: Well STEAM is great and it has done a lot of great things for PC gaming as a whole. In the end though it's a super system of DRM. I am against DRM. I love the freeware and F2P sections. I wish the freeware games on STEAM were more visible. But I can understand why they are not.
GOG is great. If I do put money one day back into the game industry, in a non-donation fashion, it would be through GOG (or a system like it) because of their no DRM policy. Why not now? Well, I have many if not all of their classic games offered. Played them when I was younger and don't see the need to get them again. Wish they had a donate button.
Humble Bundle is what retail PC gaming should be across the board. I'm not just talking about their "pay what you want" feature. I like the lack of DRM and the support provided to play the game as you want on the OS you want like Linux. As I move away from the Windows OS in 2014 and beyond I can see myself giving this group money without hesitation.
All of the other methods of PC gaming, that are no longer on disc, have been good too, IMO. They are not perfect but it looks like a bright future with so many business models doing things differently to get a piece of the pie. This is great for PC gamers because we have multiple choices and ways to get our games. Which as we can see with the Humble Bundle, are positive and progressive for the PC gaming community as a whole.
Regarding the lowering prices of PC games...this has always been a trademark of PC gaming since I started PC gaming (April to June 1988). So this is nothing new to me. It is great though and I think it helps a lot of up and coming new PC gamers get into the groove the right way.
I'm just not ready to go back into retail so quickly and beside I have a ton of freeware and f2p games to finish
